None of the above stands any logical evaluation, sorry.
There was no obvious long-standing negative effect on economy following this awful disaster.
Even the stock market has recovered by November.
And don’t say Russia benefited from US involvement in both Afghanistan and Iraq because it is plain stupid.
The first was the massive loss of Russian influence in Central Asia, as for Iraq it was a major Russian client in Middle East.

The US being bogged down in a long costly war would absolutely benefit Russia as they seek to regain military status and position on the world stage.

Russia definitely benefited from the overthrow of the Taliban and the rise of the Russian-allied “Northern Alliance.”
